See below for answers (in bold) and explanations
Step-by-step explanation:
Part A: (h+t)(x) = h(x) + t(x) = (2x-5) + (6x+4) = 2x - 5 + 6x + 4 = 8x - 1
Part B: (h*t)(x) = h(x) * t(x) = (2x-5) * (6x+4) = (2x)(6x) + (2x)(4) + (-5)(6x) + (-5)(4) = 12x² + 8x - 30x - 20 = 12x² - 22x - 20
Part C: h(t(x)) = h(6x + 4) = 2(6x + 4) - 5 = 12x + 8 - 5 = 12x + 3
Answer:
A right triangle
Step-by-step explanation:
All interior angles in a triangle are equal to 180°.
x+x+2x = 180°
4x = 180°
x = 45°
So two of the angles are 45°, and the remaining angle is 45°×2 = 90° (a right angle).
Answer:
Step-by-step explanation:
You can multiply this out to get the full equations.
It's to the 4th degree so the x on the outside has to be squared to add the fourth degree.
To get other zeros:
x + 3 = 0
x = -3
x - 4 = 0
x = 4
Hope this helped. :0)
Answer:
no one can answer this question since it doesn't show the choices, but if whichever one is 90 degrees/ has a little square in the corner would be the right answer
Answer:
The price of one pound of bell peppers is $0.6.
Step-by-step explanation:
This problem is equivalent to the following:
<em>"if 10 oranges cost $20, how much does 1 orange cost? "</em>
and the answer to that question is:
price of 1 orange = $20/ 10 oranges = $2 per orange.
Put simply, we divided the total price by the total number of items, and we shall do the same thing for the case of bell peppers:
price of 1 pound = $1.25/ 2.5 pounds = $0.5/ pound.
The price for 1 pound of bell peppers is $0.5.
